All About Marsh Pennywort (Great for BioActive Tanks)

Hydrocotyle umbellata vulgaris, aka Marsh Pennywort, is a small creeping perennial aquatic herb native to North Africa, Europe, the Caucasus and parts of the Levant. It is the plant you don't need to worry about overwatering or getting root rot, as it loves water, and the plant you almost can't kill, other than by letting it dry out of course.

Marsh Pennywort is the plant you don't need to worry about overwatering, as they can literally grow in water. It is also the plant you can't kill, because even if the whole plant dried out, you can cut the dry leaves off, add water to the pot, and they'll grow back!
